3 CONCLUSIONS
When the test results of the glass foam-sand-cement mixture
compared with the other lightweight fill materials it was seen
that glass foam-sand-cement mixture has a higher unconfined
compressive strength and CBR value. The CLSM mixture
produced using glass foam-sand-cement can be used as
lightweight fills on very soft and continually consolidating soils
for solving the consolidation and bearing capacity problems. It
can be convenient to use this mixture as fill for potentially
sliding slopes and for reducing the lateral stresses that received
by soil retaining structures.
When the results are compared, EPS mixtures have lower
unit weight and undrained shear strength values compared to
glass foam mixtures. Therefore use of glass foam will have the
advantage of higher strength compared to EPS mixtures and can
be used as a subbase material.
